Suction Sole

ABSTRACT

The Suction Sole is unique because it uses “suction cylindars” to affix itself to the bottom of the foot. The Suction Sole can be used as the sole of a shoe adding a “non-slip” function to the shoe. When the foot is inserted into the shoe, the suction cylindars take hold and prevent slippage. The Suction Sole can also be used independently from the shoe as a kind of “topless shoe” or “foot cover” that affixes itself to the foot as the person walks providing protection from the ground and traction as the person walks or runs.

This invention relates to the manufacture of a sole using suction cylinders to affix to a foot that can be used with or without a shoe. The present invention relates particularly to a suction surface designed to attach the suction sole to the foot through suction cylinders, reattaching each time the foot steps down. This invention can be used to more efficiently secure the foot inside the shoe, or it can be used without a shoe as a topless cover for the bottom of the foot.

The suction sole can be used with or without a shoe and uses suction cylinders to securely attach to the foot eliminating slippage. This can be used in conjunction with an existing sole such as the “Air Sole”. It can also be used as a topless foot cover.

There are three components comprising the suction sole:

-   -   The bottom sole     -   The top sole     -   Suction cylinders

The bottom sole is made of a hard rubber or similar material and is securely attached to the top sole. There are three functions of the bottom sole:

-   -   Provide support for the top sole.     -   Provide a hard barrier between the ground and the top sole.     -   Provide traction when the sole is used without a shoe.

The top sole is made of a softer rubber or similar material and is securely attached to the bottom sole. There are two functions of the top sole:

-   -   Provide a comfortable barrier between the bottom sole and the         foot.     -   Provide a soft surface used to form the suction cylinders.

Suction cylinders are formed in the top sole and are used to secure the foot to the sole. These are approximately 1/8 inch in diameter and are equally distributed throughout the upper sole.

As a foot steps down on the sole, the suction cylinders expand and air is pushed out of each suction cylinder.

As the foot lifts up, the suction cylinders contract creating a suction affect against the bottom of the foot, securing the foot to the suction sole.

As a person walks or runs, the suction sole reaffixes itself to the foot with every step.

BACKGROUND OF THE INVENTION

Soles have been widely used in shoes to provide a comfortable barrier between the bottom of the foot and the ground.

Formerly, the shoe itself was the primary device used to keep the foot in contact with the sole. Although a shoe would secure the foot to the sole, there is always a certain amount of slippage especially when engaging in certain sports.

Other kinds of soles have been secured to the foot through straps like many varieties of womens shoes and “flip flops”.

FIG. 3—Cut out view of the upper sole depicting the suction cylinders in their original state.

FIG. 4—Cut out view of the upper sole depicting the suction cylinders in their fully compressed view as the foot applies weight.

FIG. 5—Cut out view of the upper sole depicting the suction cylinders in their fully decompressed state as the foot lifts off the ground and weight is removed from the suction sole. The suction sole is affixed to the foot. 

1. What I claim as my invention is a sole to be used with or without a shoe that utilizes many tiny suction cylinders to affix the foot to the suction sole as the person walks or runs: This will prevent slippage when used with a shoe. It can also be used as a cover for the bottom of the foot, or a “topless shoe”.
